+/*
+Write a program that calculates and displays a person’s body mass index (BMI).
+The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height.
+A person’s BMI is calculated with the following formula:
+
+BMI = Weight x 703 / Height (squared)
+
+where weight is measured in pounds and height is measured in inches.
+
+The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight.
+A sedentary person’s weight is considered optimal if his or her BMI is between 18.5 and 25.
+If the BMI is less than 18.5, the person is considered underweight.
+If the BMI value is greater than 25, the person is considered overweight.
